The Giant Propel Advanced Pro 1 Di2 is built for riders who want to maximise speed without sacrificing ride quality. The Advanced-grade composite frame is engineered using Giant’s AeroSystem shaping, where the entire bike and rider are considered as one system. This approach reduces drag across real-world wind conditions, helping you maintain speed more efficiently whether you’re in a group or riding solo.

The integrated Contact SLR Aero cockpit and internal cable routing keep airflow clean while also delivering a precise, responsive front end. The result is a bike that feels direct under power and stable when speeds increase, especially on flatter terrain and fast descents.

A key benefit of the latest Propel design is its improved balance between stiffness and comfort. The frame is lighter and offers increased torsional stiffness for sharp acceleration, while the Vector composite seatpost and refined fork design help smooth out road vibrations. Clearance for tyres up to 32mm allows you to run wider rubber for added comfort and grip when needed.

Shimano 105 Di2 electronic shifting provides accurate, consistent gear changes with minimal effort, even under load. Paired with a wide-range 12-speed cassette, it’s well suited to both high-speed efforts and rolling terrain. Hydraulic disc brakes offer reliable stopping power and control in all conditions.

Rolling on Giant SLR 1 50 carbon wheels, the bike benefits from aerodynamic efficiency and stable handling in crosswinds. Tubeless-ready Gavia Course tyres help reduce rolling resistance while improving grip and puncture protection.

A built-in power meter on the Shimano 105 chainset adds a useful training tool, allowing you to track effort and refine performance over time.

Overall, the Propel Advanced Pro 1 Di2 delivers a fast, efficient ride with a balanced feel, making it a strong option for riders targeting speed on training rides, sportives or racing.
